Summary: Phase-gradient metasurfaces manipulate light by changing its phase locally. Our research group has developed a simple method using UV-curable resin printing to fabricate phase-gradient metasurfaces, which reduces processing time, cost, and safety hazards. We demonstrated the advantages of this method by rapidly reproducing high-performance metalenses based on the Pancharatnam-Berry phase gradient concept in the visible spectrum.

Summary: This study presents a simple one-step electrodeposition process to fabricate superhydrophobic calcium surfaces on metal substrates in an electrolyte solution, avoiding complex post-treatment. The surfaces were mainly composed of calcium myristate, dramatically reducing surface free energy and achieving a maximum contact angle of 166 degrees. By adjusting the deposition time, the surface structure can be transformed, while the superhydrophobic surfaces exhibit excellent rebound performance and surface hardness after pressing force.

Summary: A single-phase copper manganite (hopcalite, Cu1.5Mn1.5O4) was successfully prepared using a sustainable green synthesis method, which is faster and simpler compared to conventional ceramic and combustion methods. The prepared materials are polycrystalline with particle sizes ranging between 50 and 100 nm. Magnetic measurements showed that the nanostructure exhibited ferromagnetism at room temperature with an optimal saturation magnetization value.

Summary: A simple and efficient one-step strategy to fabricate electrocatalysts for the Oxidation Reduction Reaction (ORR) and Oxygen Evolution Reaction (OER) directly from agricultural cornstalks waste is presented. The method involves utilizing CaCl2 and NH4Cl activators to corrode the cornstalks and create a stable mesopore N-doped hybrid structure. The hierarchical biochar structure with synergistic effect of N, B, Fe, and Co demonstrates superior ORR and OER activities compared to commercial Pt/C and IrO2 catalysts.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
